Question 9

Different types of power stations use different energy resources.

a.

Identify which of the five power station types matches each of the three energy resources listed below.

Energy Resources:

  • Moving air
  • Water stored at high elevation behind a dam
  • Solar radiation

Power Station Types:

  • Wind farm
  • Geothermal power station
  • Hydroelectric power station
  • Solar photovoltaic (PV) farm
  • Coal-fired power station
[3]
b.

The list below describes some of the stages of generating electricity in a geothermal power station, but they are not in the correct order:

  • A: Steam drives the turbine.
  • B: Water absorbs thermal energy from hot rocks to become steam.
  • C: Electricity is generated.
  • D: The turbine turns the generator.

Complete the flowchart sequence below by identifying the correct letter (A, B, C, or D) for each blank box:

  1. Cold water is pumped deep underground.
  2. →\rightarrow→ [ Box 1 ]
  3. High-pressure steam rises to the surface.
  4. →\rightarrow→ [ Box 2 ]
  5. →\rightarrow→ [ Box 3 ]
  6. →\rightarrow→ [ Box 4 ]
